My invention relates to typewriting and like machines and pertains more particularly to means for mounting and guiding levers or pivoted members in such machines.

In some typewriting machines the construction is such that keys in the keyboard, other than those actuated, will wink, quiver, vi-' closer bearings'and guides for said levers.

But this has proved vexatious, insufficient and impracticable.

The main object of my invention is to provide a simple, inexpensive, yet highly efficient means for overcoming the disadvantages pointed out above. F j

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangementsof parts, and combinations of devices, set-forth in the following specification and particularly pointed out in the appended claims.-

In the accompanying drawings, wherein like reference characters designate corre sponding parts in the different views:

Figure 1 is a bottom plan view of a system of key levers of a typewriting machine mounted and guided in accordance with my invention. I

Figure 2 is an enlarged, detail, fragmentary, sectional view of a portion of the c0nstruction shown in Fig. 1, the section being taken on the line 2-2 of Fig. 3, and looking in the direction of the arrows at said line.

Figure 3 is an enlarged, detail, fragmentary, fore-and-aft, vertical sectional view of the same taken on the line 33 of Fig.1 and looking in the direction of the arrows at said line. Figure 4 is an enlarged, detail, fragmentary, perspective view of the combined pivot bearing and comb, together with some of the associated parts.

I have shown my invention embodied, in the present instance, in a Remington portable 927. Serial No. 197,063.

typevvriting machine, only so much of said machine being shown as is necessary to illustrate the invention in its embodiment therein. It should be understood, however, that the invention is not restricted to inclusion in such machine, but may be used in typewriting or like machines generally, wherever found available.

As shown in the present instance, the members to be guided and controlled are substantially horizontally disposed key levers 1 that extend fore-and-aft of the machine. Those levers 1 at the sides of the system extend from near the front end portions thereof, inclicated at 2, in converging planes to the rear pivoted ends thereof. On the other hand, the key levers 1 at and near the center of the systern are arranged in vertical, fore-and-aft parallel planes. Each key lever is provided at its front end with a finger key 3 and is apertured at its rear end, as indicated at 4, to provide a bearing opening to receive a pivot rod 5. i

The pivot rod is supported by a combined pivot rod support and guide comb, designated as a whole by the reference numeral 6 and preferably made of sheet metal. This memher 6 is provided with foot pieces 7 pierced to receive headed screws 8 by which said member may be firmly secured to the usual casting 9 fixed to the frame of the machine and of which supporting segments 10 and 11 form part. The member 6 is provided near the ends thereof with two oppositely curved adjacent supporting figures 12 and 13 that receive and support the pivot rod 5 near the ends thereof. Extending across the axis of the pivot rod 5, beyond its ends, are two retaining fingers 1 1 at the ends of the member 6. These retaining fingers, when in position for use and with the pivot rod 5 in place, prevent an axial displacement of said rod. When one of the fingers 14 is bent to one side a longitudinal displacement and removal of the pivot rod may be effected. Y

The pivot rod 5 is also supported substantially throughout itslength by guide arms, separating fingers or bearing members 15 and 16, depending from the member 6 and curved alternately in opposite directions to provide seats for the pivot rod. While I a spring means which coacts with adjacent levers 1 to bear laterally against them and hold them with a light pressure against the associated separating fingers or hearing members 15 and 16 which coact-with said levers to receive the lateral thrust thereof away.

from each other. In the present instance, such spring means comprise a series of coiled expansion springs 18 which surround the pivt rod 5, and each of which is received in a space 17 where a finger has been omitted from" the guide comb. Each of such springs 18 bears atone end laterally against an adjacent key lever 1 to force it with a light pressure to bear against a side edge or bearing wall 16 of a separating finger 16, whereas, the opposite end of such springbears laterally against the other adjacent key leverto force it with alight pressure against the side edge or bearing wall of the associated separating finger 15. It will be seen therefore that one spring 18 acts on two key levers to maintain them spaced apart and in lateral contact with their fixed bearingmembers, there being half the number of springs that there are key leversl The front end portion of each key lever is received and Works in a guide slot in the usual front guide comb 19, as shown in Fig. 1.

It will be understood that the springs 18 bearing lightly against the key levers axially of and near the pivot of said levers produces a slight lateral thrust against them which is resisted by the bearing members 15 and 16, thus taking up any lateral play or lost motion of the key levers without appreciably opposing the operating movement thereof, orv

rendering the type actions sluggish in operation;

It will beu'nderstood, moreover, that by this construction the key levers may be disposed at different angles to the axis of the pivot rod without the necessity of cutting guide slots in the comb at corresponding angles or having them unduly loose at their pivoted ends. Yet each lever will be effec tively held and guided .without undue restraint and a quiveringof the keys in the keyboard will be efficiently prevented.

. The construction is inexpensive to manufacture, easy to assemble, and has proven highly efficient in use.

, Various changes may be made in the con-' structlomand parts thereof may be employed without others, without departing from my invention as it is defined in the accompanying claims. I

W hat I do claim as new and desire to secure by Letters Patent, is
